There is provided an optical apparatus that provides quick and precise TTL phase difference detection and pupil slicing focus detection. An optical apparatus includes a first optical element for splitting a first polarized light component contained in light that passes an exit pupil of a first optical system and directs to a photoelectric conversion element so that the first polarized light component direct to different light-receiving areas on the photoelectric conversion element. The optical apparatus may further include a second optical element for separating a second polarized light component contained in the light from said first optical element, from the first polarized light component.

An image sensing element having a high refractive index part that covers at least a portion of each of a plurality of photoelectric converters arranged in one or two dimensions and a low refractive index part provided on the periphery of the high refractive index part. The interface between the high refractive index part and the low refractive index part has a surface that is substantially parallel to the optical axis of an image sensing lens and a slanted surface having an angle that differs from that of the parallel surface. The slanted surface is disposed on a portion of a surface near the optical axis of the image sensing lens, the portion being on a side that light rays from the image sensing lens enters the image sensing element.

This invention relates to an optical apparatus with a visual axis detection function. The apparatus having finder means for observing an object, and visual axis detection means for detecting a visual axis position of an observer who looks into a field of view of a finder comprises a visual axis input index which is arranged in the field of view of the finder means, visual axis input means for executing a predetermined function selected when the visual axis detection means detects that the visual axis of the observer is located on or near the visual axis input index and selection means for causing the observer to select the predetermined function to be executed by said visual axis input means from a plurality of functions.
摘要:
In a device for detecting the line of sight of the observer, when the detection of the line of sight is identified as having failed, the detection is effected again with a variation in the output signal of the eyeball image or in the detection threshold value for detecting the feature points of the reflected image, thereby improving the precision and the rate of success of the detection of the line of sight. The variation in the image output signal is achieve by (1) a variation in the charge accumulating time, (2) a variation in the amplification characteristics of the image sensor, (3) a variation in the current of the illuminating infrared light-emitting diodes, and/or (4) a variation in the positions of the illuminating infrared light-emitting diodes.

A focus detection apparatus includes: an image sensor that has a first pixel group which receives a luminous flux passing a first pupil area of an imaging optical system, and a second pixel group which receives a luminous flux passing a second pupil area different from the first pupil area; a storage unit that stores first and second distribution functions corresponding to the first and second pupil areas, respectively; a calculation unit that generates a first image signal by performing calculations on a first subject image, obtained from the first pixel group, using the second distribution function, and generates a second image signal by performing calculations on a second subject image, obtained from the second pixel group, using the first distribution function; and a focus state detection unit that detects a focus state of the imaging optical system based on the first and the second image signals.
摘要:
An image capturing apparatus is provided. The apparatus comprises an imaging lens, an image sensor, and a plurality of microlenses. The apparatus also comprises an image processing unit configured to generate a reconstruction image at a predetermined refocus plane by performing refocus processing on the image data that was output from the image sensor, and determine whether or not a subject appears in the reconstruction image. The recording unit of the apparatus records the image data that was output from the image sensor and record information regarding the subject that was determined to appear by the image processing unit as auxiliary information in association with the image data.
